Handheld power tools are one of the indispensable tools in production and life. Some construction workers get the tool directly after getting it, ignoring the mastery of the safe operating procedures of the tool. Any tool, improper operation is very easy to cause safety accidents. Today's new Teng industrial products procurement mro mall Xiaobian will take you to see what safety operating procedures need to be paid attention to in handheld power tools?
01
When using cutting tools, the blade should be kept sharp, intact, properly installed, and secure.
02
The use of grinding wheel tools, should first check the soft pad between the inspection wheel and the pick-up plate, to confirm whether it is installed firmly, if there is moisture, cracking, deformation, damage, bumping or contact with oil, alkali grinding wheel can not be used, and can not be wet grinding wheel pieces by themselves drying and use.
Product recommendation: Desktop grinding wheel machine
03
When working in wet areas or places where electrical conduct is easy to conduct such as metal frames, pressure vessels, pipes, etc., it is necessary to use double insulated or reinforced insulation power tools.
04
Motors and electrical appliances with non-metallic casings should not be subject to pressure and moisture when stored and used, and shall not be exposed to solvents such as gasoline.
05
The checks made before the job should meet the following requirements:
(1) The shell and handle are not cracked or damaged;
(2) The cable soft wire, plug, etc. are intact and not damaged, the switch operation is normal, and the protection zero connection is correct and firm and reliable;
(3) All guards should be complete and firm, and the electrical protection device should be reliable.
06
After the tool is started, it should be run without load, and check whether the linkage of the tool is flexible and unimpeded. When operating, the afterburner should be balanced and not too hard.
07
Overload use is prohibited. When working, pay attention to whether the sound and temperature rise, and when abnormal is found, immediately stop for inspection. When the working time is too long and the machine temperature exceeds 60 ° C, it should stop running, so that the machine cools naturally before working.
08
In the process of operation, do not touch the blade, mold and grinding wheel with your hand, and after finding that there is grinding and damage, you should immediately stop the operation for correction or replacement before you can continue to operate.
09
Handheld power tools are manually controlled by the operator, in the operation process such as hands, the tool will lose control, so that the workpiece is damaged, damage the tool, serious will also cause personal injury. Therefore, when the machine is rotating, it cannot be left alone.
Product Recommendation: Impact Drill
10
When using an impact drill or hammer, the following requirements apply:
(1) When operating, the electric drill or electric hammer handle should be mastered, when punching, the drill bit should be against the working surface, and then opened, the force should be moderate, to avoid shaking; the speed should be reduced if the sharp drop, the force should be reduced, to prevent the motor overload, it is strictly forbidden to use wooden bar to pressurize;
(2) When drilling holes, pay attention to avoiding the reinforcement in the concrete;
(3) The intermittent working system of electric drill and electric hammer is 40%, and it is not allowed to be used continuously for a long time;
(4) When the working aperture is greater than 25mm, there should be a solid working platform and a guardrail around it.
Product Recommendation: Electric Hammer
11
When using a porcelain chip cutting machine, the following requirements are required:
(1) When operating, debris and soil and stone should be prevented from mixing into the motor, and the temperature of the casing should be observed at any time, if the temperature of the casing is too high or the charcoal brush spark is generated, it should be stopped immediately for inspection and treatment;
(2) The force should be uniform and appropriate when cutting, and the force should not be too large when pushing the blade. If the blade jams, it should be stopped immediately, slowly withdraw the blade, and re-align before cutting again.
12
The use of angular grinders should meet the following requirements:
(1) It is recommended to choose a reinforced fiber resin grinding wheel, and its safety line speed shall not be less than 80m/s. The cables and plugs used together should have strong insulation and should not be replaced at will;
(2) When grinding operations, the grinding wheel and the workpiece surface should maintain an inclined position of 15 ° ~ 30 °; during the cutting operation, the grinding wheel cannot be tilted and cannot have lateral swing.
Product recommendation: angle grinding machine
13
The use of electric shears should meet the following requirements:
(1) Adjust the amount of blade clearance before operation according to the thickness of the steel plate;
(2) The operation can not be too much force, in the case of a sharp drop in the number of knife shaft reciprocating, the thrust should be reduced immediately.
Product Recommendation: Electric scissors
14
The use of nail guns should meet the following requirements:
(1) It is strictly forbidden to push the nail tube with the palm of the hand, and the muzzle of the gun must not be pointed at the person;
(2) When firing, the nail gun should be pressed vertically on the working surface, if the trigger bullet is not fired twice, the original number of shots should be maintained for a few seconds before the nail bullet is withdrawn;
(3) Before replacing parts or disconnecting the nail gun, the gun chamber shall not be equipped with nail bullets.
15
The use of a pull rivet gun should meet the following requirements:
(1) The rivet hole on the riveted part should be coordinated with the riveting bowl slip, and there should be no excessive surplus;
(2) When riveting, when the rivet shaft is not pulled, the trigger can be pulled repeatedly until it is pulled, and it cannot be forcibly twisted or pried off;
(3) When operating, if the riveting head or the handle cap is loose, it should be tightened immediately.
The above is the knowledge sharing of handheld power tools safety operating procedures, for the safety of you and others, but also for the smooth and timely construction, please be sure to use the tools correctly according to the relevant procedures.
